DIGITAL COMPUTERS

They are computers running counting numbers and making logical comparisons between factors that have numerical values.

Features of Digital Computers

Its operation is based on the count of values that are entered.

This type of computer must be programmed before being used for a specific purpose.

They are general purpose machines; given a program, they can virtually solve all kinds of problems.

They are precise, provide exactly the right answer to a specific problem.

These computers have a large internal memory, which can be introduced million characters.

These computers are the most used. At present 95% of the computers used are digital gave his very useful commercial and educational level scientist.

ANALOG COMPUTERS

Analog computers not directly computed, but constantly perceived values, signals or various physical quantities.

Features Analog Computers

They are the fastest computers. All computers are fast but the direct nature of the circuits that make up the fastest.

These computer programming is required; calculation relations are constructed and they are part of.

They are machines for specific purposes.

Dan approximate answers, as they are designed to electronically represent some sets to give you the real world, so their results are close to reality.

These are generally used to monitor the conditions of the real world such as wind, temperature, sound, movement, etc.

HYBRID COMPUTERS

Hybrid computer is a system built a computer and an Analog Digital, connected through an interface that allows the exchange of information between the two computers and the development of their work together.
